摘要： A transmission device for a motor vehicle includes a planetary gearset and a spur gear differential. The planetary gearset includes a drive sun gear, a ring gear fixed to the housing, and multiple stepped planetary gears. Each stepped planetary gear has a first gear meshing with the drive sun gear and a second gear meshing with the ring gear. The spur gear differential includes multiple first and second compensation gears. Each first compensation gear meshes with a first output sun gear, each second compensation gear meshes with a second output sun gear, and the first and second compensation gears mesh with each other in pairs. One compensation gear of each compensation gear pair is arranged in phase with a respective stepped planetary gear. The other compensation gear of each compensation gear pair overlaps axially and contactlessly with the second gear.

摘要： An electric drive provides transmission oil cooling. An oil circuit supplies the transmission with oil. A cooling circuit cools a supply device and/or an electric motor with a coolant. A heat exchanger portion is coupled on one side to the cooling circuit and on the other side to the oil circuit. The supply device is arranged in a supply housing region. The heat exchanger portion forms a wall portion of the supply housing region. An end cover closes the heat exchanger portion. The end cover has at least one functional region, wherein the functional region is designed as a counterpart cooling structure, as an oil sump region and/or as a pump interface for coupling an oil pump.
